Comprehensive Analysis of Key Features in ET03 Car Jump Starter
Feature
Description
Peak Output Current (2500 Amps)
Excellent
The ”peak output current” represents the maximum burst of current the jump starter can deliver to start a vehicle. At 2500 Amps, this is significantly higher than the market average of around 1000-1500 Amps, making it highly effective for larger engines and cold weather.
Battery Capacity (20,000 mAh)
Good
The battery capacity determines how many times the device can be used before recharging. The high capacity of 20,000 mAh exceeds typical jump starters (approx. 12,000-15,000 mAh), ensuring extended usability for multiple jump starts and device charging.
Supported Engine Size (up to 8.0L Gas, 7.0L Diesel)
Excellent
This metric measures the versatility of the jump starter. The ability to support large gas and diesel engines surpasses most competitors, which typically cover 6.0L gas and 4.0L diesel engines, underscoring its robust performance.
Additional Features (USB Ports, LED Light, LCD Display, Storage Case)
Good
These auxiliary features enhance functionality and ease of use. While standard USB ports and LED lights are common, the inclusion of an LCD display and storage case offers improved convenience, highlighting the product’s thoughtful design.

Unpacking Real Customer Reviews: The Strong and Weak Points of the ET03 Car Jump Starter
A lifesaver during tough car troubles. Dhyana Wallace praises this device for being “essential” when her car required a jump start every morning due to ongoing issues. She loved its compact size, stating it “fits in my trunk and is easy to carry” and appreciated the LCD display for monitoring its status. Additionally, the LED light proved invaluable for nighttime use. Dhyana insists this product is “definitely worth the investment” for anyone relying on a portable jump starter.
Handles larger vehicles with ease. According to Spencer, the ET03 performed flawlessly on his diesel F250 in freezing Minnesota temperatures. What stood out to him was the jump starter’s capacity and ability to recharge quickly when paired with the correct charging cord. Spencer claimed it was “super handy” and even used it professionally as a snowplow driver to assist customer vehicles multiple times. Truly an “economical, great-priced” powerhouse!
Dependable for diverse emergencies. Paula Craig used this jump starter on her car six months after purchasing it, and it retained a 100% charge. She found it “easy to follow directions” and added that “it worked like a charm” when she needed it most. So impressed, she bought another one for her daughter. Paula wholeheartedly “highly recommends” it for reliability during emergencies.
Unreliable performance in critical moments. Bobbie Sue Kincannon recounted repeated issues with jumpstarting trucks and even a smaller boat battery. The device didn’t deliver enough power on any of the three occasions it was tested, which made her feel it was a “waste of money.”
Discrepancies with product quality and accessories. Shania expressed disappointment with her purchase after realizing too late that the connectors provided with her ET03 jump starter “don’t fit the port required” to use it properly. Though she found it useful as a phone charger, it couldn’t fulfill its primary purpose, leaving her stranded.

So I have attempted to use this device 2 times now And if you are wanting a box to carry around and just watch the display gauge go from 100% to 5% and not actually do anything then this is for you The times I have tried using this it has not worked not even enough to spin the starter in a small car I guess it works best to use it as a flashlight and portable battery charger for your phone Just don’t rely on it to start anything

Nothing bad to say about it whatsoever
The media could not be loaded. I bought two of these to have as a safety jump battery for my son and daughter’s car. It works just as well as another car battery. It started my daughter’s big V8 in the dead of winter without any struggling at all. I even left it in the car over the cold Colorado winter and it didn’t loseuch charge and was able to start her car immediately. I can’t say anything bad about these things. Everyone should have one in their car

Awesome, Incredible, Could be Lifesaver
This small device just removed at 10-ton weight from my chest. No more battery worries!! It’s well made, well packaged, and the instruction manual is very well written. You can always tell a lot about a company by reading their manual, if you’re lucky enough to even get a manual! The quality of the manual tells me the company cares, from inventing, designing all the way down to the customer population. After a call to the company, I believe this to be true. For those who need a wall adaptor, the manual says the adaptor needs to be >5V, but that’s not correct. Anyone who’s tried to find a suitable adaptor that’s >5 volts goes into a tailspin trying to figure out what to get, and from where. So I called the maker and confirmed that a 5V adaptor is fine, and I can attest that it works great. For those looking to keep this in their vehicle 24X7, I’d think twice about that. Read the manual or call the co. for more info. The severe winter and summer temps, in a closed vehicle, can get pretty ferocious, and lithium batteries are not all that friendly or safe. If you insist, then at least carry a fire extinguisher suited for lithium. Maybe carrying it all in a small styrofoam chest could help maintain a more moderate temp for them. I love, love this product!!

I rarely write reviews because I have been so disappointed by many products. But when I do come upon an item that does as it claims, I feel compelled to share something. Having no one to assist in jumpstarting, and after checking into the cost of having such service, I decided it would be more cost-effective to purchase this item. Each time I ventured out, this product worked flawlessly. Having used it several times before having the battery checked, I would highly recommend it. I did need a new battery. If you follow the directions, charging, storing, and using are a cinch.

I’m always unsure about if these battery packs will have enough to jump start my vehicles. I was totally wrong. This is amazing. I have charged it once and have used it on both of my 2500 trucks and it jump starts them. You can charge accessories that have a usb plug in and it’s fast. It has a real nice case to store everything in.

Make sure it works while you can still return it
I rarely write bad reviews, but when I need a gadget to work in crisis situation, and it doesn’t, I feel I should let others know about it. It worked once. Two weeks later when I needed it again, it no longer worked. Battery was charged to 100%, light worked. I called customer service, she tried helping me on the phone, but nothing she suggested helped. 30 days already went by and I wanted to return the jump starter but they wouldn’t let me. Customer service left me waiting forever, then wanted me to take pictures. Then she finished conversation before telling me what I should do with pictures. It was like an episode of Twilight Zone…

Jumped my van (Town & Country V6) yesterday and it was still at 88% after the jump. Even used it as an emergency light and phone charger during a power outage for a few hours. It has exceeded my expectations. Don’t let the price fool you it is a power house. I’m buying a few more for each of my vehicles.

Best purchase ever…. If you are smart enough
A lot of negative reviews about this portable charger, I’ll explain why that is and how to easily avoid having that issue . I have a 2019 F250 Diesel with a 6.7L and I live in MN. I have to jump my truck as I haven’t installed a trickle charger etc and the extreme temps kill batteries quick. This things capacity is insane. I clip it on and usually can start my diesel withing 3 seconds, using less than 5%. Now. For the people who say it cannot hold a charge, or won’t charge after using it. You must, I repeat MUST use the charging cord provided or one with the exact same specs, it’s insanely picky. And use a quality hub to plug the cord into and you will have amazing results. I’ve had it two months and have used it 40+ times as I a a snow plow driver and use it to jump customer vehicles as well. Super Handy, economical great price.

Today a friend of a friend ran out of gas and killed her battery trying to start the car anyway. After I put a gallon of gas in her car, I used this jump starter to get the car started. The jump starter drained from about 90% to 44% in about three minutes, but it started the car. I’d call that a win!

I have now had to use this twice. Each time was on a completely dead battery. Once was on my 2010 Mercury Milan. Realized I needed to allow it to boost the battery for a few moments before I tried to start it. Worked terrific. Second use was on my 2013 explorer. Accidentally left it on in accessory mode over night in sub zero temp. The battery was completely dead. Allowed the booster to charge for a few moments. The explorer fired right up. Great product.

Each time I ventured out, this product worked flawlessly. Having used it several times before having the battery checked, I would highly recommend it. I did need a new battery. If you follow the directions, charging, storing, and using are a cinch.

Worth the money!
I’m always unsure about if these battery packs will have enough to jump start my vehicles. I was totally wrong. This is amazing. I have charged it once and have used it on both of my 2500 trucks and it jump starts them. You can charge accessories that have a usb plug in and it’s fast. It has a real nice case to store everything in.

Make sure it works while you can still return it
I rarely write bad reviews, but when I need a gadget to work in crisis situation, and it doesn’t, I feel I should let others know about it. It worked once. Two weeks later when I needed it again, it no longer worked. Battery was charged to 100%, light worked. I called customer service, she tried helping me on the phone, but nothing she suggested helped. 30 days already went by and I wanted to return the jump starter but they wouldn’t let me. Customer service left me waiting forever, then wanted me to take pictures. Then she finished conversation before telling me what I should do with pictures. It was like an episode of Twilight Zone…

Works well
I purchased this item over 6 months ago. It has worked for multiple jumps on a F150 5.4 without recharge on the same day. Jumped my van (Town & Country V6) yesterday and it was still at 88% after the jump. Even used it as an emergency light and phone charger during a power outage for a few hours. It has exceeded my expectations. Don’t let the price fool you it is a power house. I’m buying a few more for each of my vehicles.

Best purchase ever…. If you are smart enough
A lot of negative reviews about this portable charger, I’ll explain why that is and how to easily avoid having that issue . I have a 2019 F250 Diesel with a 6.7L and I live in MN. I have to jump my truck as I haven’t installed a trickle charger etc and the extreme temps kill batteries quick. This things capacity is insane. I clip it on and usually can start my diesel withing 3 seconds, using less than 5%. Now. For the people who say it cannot hold a charge, or won’t charge after using it. You must, I repeat MUST use the charging cord provided or one with the exact same specs, it’s insanely picky. And use a quality hub to plug the cord into and you will have amazing results. I’ve had it two months and have used it 40+ times as I a a snow plow driver and use it to jump customer vehicles as well. Super Handy, economical great price.

Awesome charger
Just used this yesterday on cold, dead battery. Worked great in seconds and so easy to hook up for this senior lady. So glad I bought it!

“Houston We Got a Problem”
I did look at the reviews for this charger. I don’t know if I got a bad one; but it wouldn’t charge either of my Pontiac or Chevy batteries that I left a console light on. Thankfully I have a set of Jumper Cables. I hope to return it for a refund with Zevo. I’m glad it happened at home and at my unit where I keep the Show Truck.

I can confirm it works
Today a friend of a friend ran out of gas and killed her battery trying to start the car anyway. After I put a gallon of gas in her car, I used this jump starter to get the car started. The jump starter drained from about 90% to 44% in about three minutes, but it started the car. I’d call that a win!

Works as it should.
I have now had to use this twice. Each time was on a completely dead battery. Once was on my 2010 Mercury Milan. Realized I needed to allow it to boost the battery for a few moments before I tried to start it. Worked terrific. Second use was on my 2013 explorer. Accidentally left it on in accessory mode over night in sub zero temp. The battery was completely dead. Allowed the booster to charge for a few moments. The explorer fired right up. Great product.

Doesn’t work
Bought for our son for Christmas, made sure it was fully charged. He tried to use it 3 different occasions and would not put off enough power to crank his truck. Tried on smaller boat battery wouldn’t work for that either. Waste of money!

Did not include the right ports
I bought this a while ago in November or so. I charged it up and since I don’t know much about these items, I thought that when the times comes I’ll just keep it in my car. So the time came and my car died. It’s February now and I am trying to connect the wires to the charger and it’s the wrong port… the wires don’t fit the port required. I checked and other’s got the right one in the reviews. I must have received a faulty one and not realized until it was too late. Anyways it’s useful as a portable charger for a phone! A lot of battery life but did not help with my car as originally anticipated.

Powerful and portable.
I had to used to help another driver on a highway. Doesn’t take space on your trunk, and is really powerful.

Worked perfectly!
Charged this when purchased 6 months ago. Still had 100% charge when I needed it today. Easy to follow directions . It worked like a charm. My car started immediately. Just bought one for my daughter. I would highly recommend!
